what is Wrapper?

what is Wrapper?

We overwrite the original function into user friendly function.That function is called as wrapper.


For Example below consider the original function have 5 argument and it process those five argument


public void originalFunction(string arg1,string arg2,string arg3,string arg4,string arg5)
{
//Some processing happening by the use of those parameter
}


For the above example consider if we only often need to send 3 parameters. we no need to send another 2 parameters.

We can create a wrapper function and internally get call that original function:

Example:

public void WrapperFunction(string arg1,string arg2,string arg3,"","")
{
originalFunction(string arg1,string arg2,string arg3,"","");
}


For above WrapperFunction is a "Wrapper" for originalFunction. Above we just hard coded the unnecessary last 2 arguments.
